GENERAL DESCRIPTION OF THE ADSST-73360LAR
ADC
The ADSST-73360LAR is a 6-channel input analog front end
processor for general-purpose applications, including industrial
power metering or multichannel analog inputs. It features six
16-bit A/D conversion channels, each of which provides 76 dB
signal-to-noise ratio over a dc to 4 kHz signal bandwidth. Each
channel also features an input programmable gain amplifier
(PGA) with gain settings in eight stages from 0 dB to 38 dB.
The ADSST-73360LAR is particularly suitable for industrial
power metering as each channel samples synchronously, ensur-
ing that there is no (phase) delay between the conversions. The
ADSST-73360LAR also features low group delay conversions on
all channels.
An on-chip reference voltage is included with a nominal value
of 1.2 V.
The ADSST-73360LAR is available in a 28-lead SOIC package.
